Modern approach methods of geography, ecology, quantitative analysis, expert integration, remote sensing image analysis and geographical information system were combined to reveal the matters in this paper. The eco-geographical background of the research area and the research work studied by other scholars were comprehensively expatiated. The temporal and spatial variation of precipitation and soil moisture, vegetation and soil distribution, and land use/land cover were compared as well. On the basis of foregoing analysis, the eco-geographical differentiation was discussed. According to principles and indicators, with extension engineering method and integrated analysis, the physical geography boundary between subhumid and semiarid areas were demarcated. By using remote sensing image analysis, wavelet analysis of the perennial precipitation and temperature, and the comparison of temporal and spatial variation of the desertification, this paper accounted for the regional response to global environmental change and suggested the dominant environmental problems.

It expanded to 106119ha in 1973, descented to 99167ha in 1987, backed up to 112440ha, and attained the max value in history—123170ha in 1998 and descent to 109934ha again in 2001. GIS overlaying analysis shows that, the spatial change of Minqin Oasis had the different characteristics in different stage in the last 50 years: at the end of 50's to the beginning of 70%, oasis expandation Was performed by extension of origin oasis; the atrophia of oasis from the beginning from 70's to the 80's was performed by increasing of non-oasis spot pieces of inner part for oasis; the main performance of keeping on expanding of oasis from late 80's to late 90's is outside extension of Baqu oasis near the upper stream, with increased oasis area in interior of hungriness and increased area of non-cultivation in Huqu oasis in the north. From 1998 to 2001, opening up wideness in interior of hungriness continued, but hnngrinessization of oasis became worse. The oases in the Minqin Basin developed from small to large and back to small in terms of area changes, and from south to north then to south in terms of spatial changes.

绿洲分布图的GIS叠加覆盖分析表明，近50年来民勤绿洲的空间变化在不同阶段有不同的特征：50年代末至70年代初，绿洲扩展主要表现为已有绿洲的外延式扩大；70年代初至80年代后期的绿洲萎缩，主要表现为绿洲内部非绿洲斑块增加；80年代后期至90年代后期的持续扩展，主要表现为靠近上游的坝区绿洲向外围扩展和荒漠腹地绿洲面积的增加，而北部湖区绿洲弃耕面积不断扩大；98年至2001年，绿洲荒漠腹地的开荒还在继续，但湖区的绿洲荒漠化还在进一步加剧。50年来民勤绿洲的发展总体上经历了一个面积由小到大再到小，空间位置上从南而北再向南的迁移过程。
